In Episode 13, the three begin training together, and are tasked by Kuma with coming up with a unit name. Sophie helps Laala to come up with an autograph, which she has been struggling with since Episode 3. The girls also meet a big fan of theirs - Hanana - whom Laala gives a Friends Ticket to.

Sophie asks Laala and Mirei to call her "Sophie" without the suffix "-san", and she and Mirei then come up with two ideas for the group's name. Laala thinks of combining them together into SoLaMi♡SMILE. During the girls' second performance and unit name debut, they showcase a brand new set of Cyalume Coords made by Sophie's older sister Cosmo.

In Episode 27, following their loss of the Paradise Tiara and the Paradise Shoes to Faruru, the girls split from SoLaMi♡Dressing and continue activities as SoLaMi♡SMILE, performing a concert to kick off the new year. In Episode 29, they undergo training from Gloria and Love to prepare for the final Paradise Prize competition.

In Episode 30, the girls face off against both Dressing Pafé and Faruru and end up losing to Faruru, who obtains the entire Paradise Coord set. In the following episode, they enter a slump due to their loss, but are eventually cheered up after a performance from Sophie's older sister, Cosmo.

In Episode 34, Mirei decides for the group to write an original song so they can increase their chances of winning the Paradise Coord back from Faruru. After an incident with Unicorn that resulted in Faruru's toy (dubbed Faruru's "Non" by Faruru herself) getting broken, the girls and Dressing Pafé, who had also been attempting to write an original song, (unknowingly) receive lyrical inspiration when Faruru asks them "What is a friend?"

Laala suggests for the two groups to once again team up as SoLaMi♡Dressing, and in Episode 35, they unveil their new song - Love friend style - against Faruru, winning the Paradise Coord. In Episode 37, the girls perform as a part of SoLaMi♡Dressing to wake up Faruru from her sleeping state.

In Episode 38, see Faruru and Unicorn off on their journey. In the same episode, they are informed by Meganii that both SoLaMi♡SMILE and Dressing Pafé are officially disbanded. In Episode 39, they are given an explanation for their disbandment - PriPara has undergone some recent changes. Due to the construction of the Dream Theater, the system now requires groups to be made up of five members.

The girls spend the following episodes performing as an individual idols, and are continuously prevented from reforming their unit by Kuma, who has been tricked by Neko into thinking that he will become torpid if SoLaMi♡SMILE comes together again.

In Episode 43, Kuma witnesses how much Laala, Mirei, and Sophie wish to perform together once again and with his encouragement, the trio win a competition that awards them with the honor of performing as the Dream Theater opening act. The girls undergo another unit ceremony and reform SoLaMi♡SMILE, allowed to perform as a three-person team due to the lack of groups that have successfully assembled five members.

Unit Relationships

All three members of SoLaMi♡Smile generally get along with each other, as they balance each other out. At first, there were some disagreements due to Sophie's refusal to train; but now they rarely happen.

Etymology

The first part of their unit name - SoLaMi - was thought up by Sophie and is taken from the first syllables of the girls' names - Sophie, Laala, and Mirei. Mirei uses Sophie, Mirei, an I for "ai" (愛 lit. love), Laala, and an extra E at the end to come up with "SMILE". Laala thinks of combining the two into SoLaMi♡SMILE which collectively means "Look up at the sky and smile" (空見て笑って,Soramite waratte).

Trivia

Their unit logo incorporates the girls' hair accessories of their original Cyalume Changes.

This showcases the sixth time in the Pretty Rhythm / PriPara universe in which an idol's name is used as the basis for the unit name, following MARs, Serenon (with K), COSMOs, Happy Rain, and Bell Rose.

Their name can be considered a Japanese pun.

They don't have an official leader, but one could argue that Mirei functions as the de facto leader due to her tendency to take charge and plan out the group's next move (such as writing original lyrics for their third unit song).

The order they performed their solo lives is the same order their names come up in the "SoLaMi" as Sophie was the first to have her solo live, Laala had her solo live later and not long after Mirei had her solo live.

Mirei is the only member who has not been center.

The order their name is in mirrors MARs- Having the Cool idol of the group on the left, the Lovely idol in the middle, and the Pop idol on the right.

Their positions on stage mirrors Happy Rain♪- Having the Pop idol of the group on the left, The Cool idol on the right and the Lovely idol in the middle.

They are the first known idol group to perform 4 consecutive concerts.
